Class Information
Number: 310/65
Name: Electrical generator or motor structure > Dynamoelectric > Rotary > Cooling or fluid contact > Circulation > Heat-exchange structure > Spacers (e.g., laminae, coils, etc.)
Description: Subject matter in which the means for facilitating, augmenting, or modifying the transfer of heat includes devices for maintaining parts of the dynamoelectric device out of contact with each other, so that either the cooling fluid has access to enlarged areas of the device or face-to-face heat transmitting contact is avoided.
